A system for determining a communication protocol of a communication device operating on digital subscriber lines includes a communication server coupled to a number of subscribers using a number of subscriber lines. The communication server comprises a first communication device that communicates with a second communication device using a particular subscriber line. A processor coupled to the communication server determines that the first communication device is inoperable to communicate with the second communication device using a first communication protocol. In response, the processor initiates the operation of the first communication device using a second communication protocol.
